Barrow's DDC is loud even in 3000 rpm, D5 is too big for an itx build. Finally I got a DDC310 from alphacool.It works well and quietly. With EK-XRES 100 DDC - Acetal, it's low enough to put it in the case.

For the GPU part, it's hard to found a waterblock for EVGA 1080ti sc2. I got one from bykski. However, it's a little bit big in ncase. So I got a L-shape block for it and use a thin radiator to fit them inside the case.

To have more cooling capacity, I bought a 92mm radiator and put it at the rear of the case.

For the custom cable, I got 40cm for CPU, 25cm for 24-pin, 18cm for GPU and 15+5 cm for SATA.

Since it's the first time for me to to the custom loop, I got a lot of fittings rather than bend the tubes.

Maybe I'll bend them more in the future. And I'll buy higher feet for the case.
